Sumatran Robin

Small, distinctive nightjar, pale gray overall with dark brown spots. Note the white eyebrow and moustachial stripe. In flight, males exhibit white underwings and undertail and black flight feathers. Found at a precious few open savanna grassland sites with scattered trees, especially those with numerous termite mounds known as earthmound fields.

Large dark pigeon of forest interior. Overall purplish-gray, slightly darker and browner on wings. Pale eye. Sexes alike. Note plainer appearance and longer tail than many other doves and pigeons. Most similar to Ruddy Pigeon but plumage grayer (not reddish) and eye paler. Usually quite secretive, staying in the canopy where singles or pairs feed on fruits. Found from lowlands into subtropical zone, up to 2,300 m (7,500 ft). More often heard than seen; listen for the cooing “who-cooks-for-you” song with the last two notes drawn out.

Stocky, brown heron found in extensive reedbeds; typically very secretive. Seen mainly as single birds in flight, especially early and late in the day. Stealthy and easily overlooked; cryptic plumage blends well with reeds. Note tawny-brown face and neck, blackish cap, streaked upperparts. Bizarre "booming" song often reveals presence. Compare to juvenile Black-crowned Night-Heron, which has pale-spotted upperparts and is often seen in trees (bitterns usually on or near the ground).
